Imphal Valley Remote Sensing and Geographical Information Systems
2013/3/11
Landsat ETM+ data and SRTM DEM data were used to delineate the geological, structural and geomorphological features in the intermontane Imphal Valley in Manipur, India. This area has simple geology, s...
Synergetic Use of Satellite Image and DEM for Identification of Landforms in a Ridge-Valley Topography
Geomorphology Resourcesat-1 ASTER India
2013/3/8
Multispectral satellite image and digital elevation model (DEM) have emerged as the primary data sources for the mapping of landforms. They offer an opportunity to gain a fresh insight into the geomor...
Optimal Scale Selection for DEM Based Slope Segmentation in the Loess Plateau
Optimal Scale Multiresolution Slope Segmentation Loess Plateau
2013/3/7
Optimal scale selection is the key step of the slope segmentation. Taking three geomorphological units in different parts of the loess as test areas and 5 m-resolution DEMs as original test date, this...
The SRTM DEM, a digital elevation model based on the Shuttle Radar Topography Mission of February 2000 is a source of elevation data with nearly worldwide coverage. It has proven its usefulness in var...
基于DEM的流域特征提取综述
DEM 流域特征 河网
2007/12/20
回顾了自DEM出现以来它在流域特征提取方面的应用和发展，论述和比较了提取流域特征的各种方法。包括确定流向的单流向法（D8法、Rho8法、Lea方法、DEMON法以及 D∞法）和多流向法；提取河网的识别谷点法和基于流向提取河网的方法；提取河网过程中洼地和平原区的流向确定、河网提取的方法；划分子流域和提取流域边界线的方法；计算分布式子流域特征的方法，其中重点论述了子流域长度和坡度的计算方法，以及提取控...
